SOLID ELECTROLYTE FUEL CELL AND METHOD OF PRODUCING THE SAME

摘要

A solid electrolyte fuel cell comprising an air electrode, a solid electrolyte film, a fuel electrode, and an interconnector, wherein a somewhat dense ceramic layer having a gas permeation flux Q1 of 50 m.hr<-1>.atm<-1> or less is formed on the air electrode, and on this ceramic layer an interconnector film, which is a dense ceramic film, is formed. The gas permeation flux Q2 of the interconnector film is 0.01 m.hr<-1>.atm<-1> or less. This value is preferable to an interconnector film of a solid electrolyte fuel cell.
